Yes, it turned out that all the man files (even those that claimed that
emacs would be installed under /usr/local) were all part of the debian
install, and were in the right places. The two directories it was
complaining about were part of the proper install, and after they were
recreated the warnings stopped. Just goes to show how often the problem
you think you have isn't the one you actually have.

Yup, that was exactly right.

Thank you!
